Abstract: Taking a certain type of engine nozzle as the measurement object, this paper proposed a rapid measurement method-using high-precision noncontact measuring instruments, such as laser radar, to measure engine thrust line. The error simulation analysis shows that this method has high measurement accuracy, high measurement speed and low cost. Therefore, it has broad space for development in the aerospace engineering measurement system.
Key words: Engine, Thrust line, Fast measurement
